Government pensions are unsustainable and at some point yearly expenditures will be more than entire state and city budgets. New employees need to be put in 401k's like the rest of us.
401k's are also unsustainable because people fail to adequately provide for their own retirements. The nexus of low savings rates, unpredictable markets, stagnant wages, decreasing labor force, and the increasing reliance on 401ks will cause huge problems that are completely unrelated to pensions, but will ultimately result in remedies that will probably be more costly than adequately funding pensions.
This is humorously libtarded on many levels. So, 401ks are "unsustainable" because people are too stupid to fund them? Sounds like that's a problem with the people - not the investment vehicle.
I also like the acknowledgement of stagnant wages and a dimishing labor force. You know what will fix that? More liberal tax and spend redistribution of weath, like stuffing pension funds, amiright?
And then there's the "welp, we're better off just stuffing tax dollars into pensions instead of paying to take care of people later on" - 'cause those are totally the only two choices.
You know what would be a good policy? Phase in a complete dismanteling of KPERS, replacing it with modest wage raises.
